A metal material refers to a material having properties such as gloss, ductility, conductivity, heat transfer and the like. Generally divided into ferrous and non-ferrous metals. Ferrous metals include iron, chromium, manganese, and the like. Steel is the basic structural material called “industrial bone”. Due to advances in science and technology, the wide application of various new chemical materials and new non-metallic materials has led to an increase in the number of substitutes for steel and a relative decline in demand for steel. But so far, the dominant position of steel in the composition of industrial raw materials is still difficult to replace.
